The Ultimate Guide to Downloading and Managing Images for EVE-NG

EVE-NG (Emulated Virtual Environment – Next Generation) is the gold standard for network engineers, DevOps professionals, and certification candidates (CCIE, JNCIE, etc.) who need to build complex virtual labs. However, a common point of confusion for beginners is this: EVE-NG is just the player; the devices (routers, firewalls, servers) are the images you must provide.

Dynamips: A legacy emulator for older MIPS-based Cisco routers (e.g., 7200, 3725). It uses actual Cisco IOS .bin files and is less common in modern labs due to its limited hardware support. 2. Where to Legally "Download" Images Add Network Device Images to EVE-NG from CML Download-- Eve-ng Images

Check folder name. | | "Permission denied" in logs | Forgot to run fixpermissions script. | | Console shows "Boot failed" | Tried to use a Cisco IOL image in a QEMU folder (or vice versa). | | Extremely slow boot (10+ min) | Not using a proper virtio disk. Convert raw .img to qcow2. |

  1. Use Symbolic Links for Large Drives: If your EVE-NG root disk is small, store images on a secondary drive and symlink /opt/unetlab/addons/qemu to it.
  2. Compress Images: Use qemu-img convert -c to create compressed qcow2 images (saves ~50% space).
  3. Backup Your Images: The /opt/unetlab/addons/ folder is the most valuable part of your setup. Back it up weekly.
  4. Version Locking: Document which image version goes with which lab. A lab built on IOSv 15.7 may break on 16.3.
